. Application filed January 28, 1920.; Serial no. 354,547.

To all w ham it may concern Be it known that I,'AN'ro INoLo Ciis'ro,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in ChangeableExhibitors, 01-

which the following isa specification.

This invention relates to an advertising,

device in the nature of a changeable exhibitor operatedby. an electric motor and more particularly adapted for use with a razor honing machine otthe type set forth in my prior Patent No.- 1,091,939, granted 'March 31, 1914.

Among the objects of myinvention is to provide adevice which is simple and. inexpensive in construction and which may be operated by the motor on themachine with which the device is used, and further to ef-' feet the changing of the signs by having the motor intermittently rotate a member carrying the signs and thus bringthem into view through windows or openings in the casing surrounding the sign carrying nemben. I

The invention consists further in the mat ters hereinafter described and more particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a front view of an advertising device constructed in accordance wlth my invention and shown as mounted on and operated by the motor of a razor honing'machine of the type mentioned, only so much.

of that machine being illustrated as toindicate the manner in which the rotatable sign carrying member is connected with and op-.

erated by said motor;

- The advertising devi-ire of .my invention, as shown' inthe drawings, comprises a tubular. casing 1, arranged with its marginal Wall verticaland preferably cylindrical in shape, although any other shape for ornamental or otherpurposes may be employed f desired. In the marginal. wall of the cas-' ing areone or more windows or openings '2, 2, preferably rectangular in shape, and, as shown in F ig.- 1, two windowsare pro vided andarranged one'above the other, so thattwo signs, arranged in a like manner,

, may be displayed through said windows at the same time, when brought there 'for that purpose. Locatedin the casing 1 is a memsame shape and size as its associated window so as to extend across the same .When brought into view.

The casin'g 1 and the membe'rB are both mounted on an upright fpost or standard 5, secured to a supporting base] 6, [which as shown in the drawings is the base of a razor honing machine, although itis to be of course understoodthat the base may be used for the advertising device alone when the latter is not mounted on and used wlth a razor honing or other I machine.

The casing 1, as shown, is open at the top and bottom, and, to mount it on the post, said casingis provided at its bottom with a plurality of inwardly extending, radial arms 7 7. Theouter ends of said arms are secured to the marginal wall of the casing, and the inner ends of said arms are secured to a collar 8, applied on the post 5 and rigidly. fastened thereto by asset screw 9, or in any other preferred manner. The member 3 is cylindric in shape, and is formed of top and bottom rings 10, and an intermediate ring 11, all secured together by aplurality of vertical strips 12; These are spaced apart circumferentially, preferably the same distances, and divide the member 3into a plurality of card or sign holding sections. The member 3 is also open at top and bottom, and; to'connect it with the post 5. said member 3 is provided at its bottom with "a plurality of radially arranged spokes 13, 13, the inner ends of which are securedto a collar ll applied on the post 5 above the collar 8, asshown in Figs. t and The spokes 13 have their outer ends bent upward, as indicated at in Fig. 6, and are secured to the insid'e'oi the rings 10 and 11 to the rear of the vertical'stri 'j as shown. The collar 14 restson the collar8 and is loosely mounted on the post 5; which isheld" stationary by its connection with the base 6. Tliu's,1 thc member 3' may he turned or rotated about the post 5aiidwithin the casing lywhiclif is also held stationary byits connection with saidpostl The collar 14 is held against the coll r 8 by a coil spring 16 surrounding the post 5 above'the cOll:i1 l4l:, and the compression of said spring may he vaseam willby a nut ,17screwed on the upper end of the post 5, as shown inFig. l. The

of the spring on the collar lt is s'utiicient to holdthe member 3 against rotation when it is not being rotated or turned by the power driven mechanism provided for that purpose and to be presently described, arich as the member isonly intermittently rotated by such mechanism, it follows that said member has periods o'l rest, and thus will holdtoview, at the windows2, certain of. the cards l duri ig such periods. To illuminate the display or advertising cards at lrOmwithin the casii'ig l and when at the windows 2,1 provide an incandescent lamp 18" held in a lamp socket 19 applied on the iq'i'per end. of the post 5 above the nut 17, as 'shown, v i For imparting intermittent rotation to th'e niember 3' and thus bring the cards 4 carried thereby successively into view at the win' ("()ws 2, I provide mechanism constructed as renews. Applied toth'e post 5 below the collar S is collar 20 fixed thereto in any preferred mannera as by a set screw b'aid collar 20 is spaced the distance required below the collar 8 by airint erposedg slee which may be made integral with either of said parts. F xed to said collar 2a) and entending horizontally outward therefrom is a shaft 23, on which is loosely mounted a sprocket wheel 24, the hub of which carries a fined pin 2 5 a'rranged substantially right-angles to the shaft 23 and having alength to reach the spokes ofthe incmberQ-l for interiiiittent y rotating tlie same. In the particular :liorm of construction illustrated, the pin is secured following manner.

to a collar 26, which is fastened to the hub of said sprocket wheel by a set screw 27, and the sprocket wheel is held from movement oi? the shaft 23 by a stop collar 28. This construction is provided to facilitate assembling the parts and also disassembling themi'or the purpose of repair and adjustment. Vhen the sprocket wheel 24 is retated, the pin is carried upward against one of the spokes 13 standing in its path of movement, and the member 3 will be rotated as long as said pin 25 remains in contact with such spoke. The parts are so arrangedand proportioned that this period of movement is-sutficientto carry one set of cards or signs l away from the windows 2 and bring the following set to the windows for display in place of the set previously displayed; Assoon as such set of signs are brought into full display position; the pin 25 moves out of contact with the spoke and the memlicr 3 is heldfro'm further rotation by the spring 16, am the signs brought into view at the windows remain there until the pin 25inoves into contact with the folloi'virigspoke l3; \Vh'en that happens. the member 3 is again rotated to bring" the next set of signsinto view at the windows, and this intermittent rotation of thelmember 3 continues as long as the sprocket wheel 24 7 about tlie'casing 1, additionalwindows could be provided.

Any type of power driven means could be used for rotating the sprocket wheel 241. but when the advertising device is used with a razor honing machine oi the type mentioned, the SDITOCl iGt wheel 24 is driven from the electric motor'29 of that machine, in the As shown, the motor 29 is mounted on the base 6, and to its arniature shatt is secured a grooved pulley 30,

over which is trained a belt 31,* which also extends about a larger grooved pulley 32 journaled on the base 6. This pulley has an inwardly extending hub grooved: to receive a belt 33, which is tra ned over a grooved pulley 34 mounted on a shaft 35 j ou rnaled standards on said hase'G. At the inner end of said shaft 35 is a gear pinion 3G in mesh with agear wheel 37. on the shaft of which is a gear pinio'n 33, which meshes with a gear wheel 39 mounted on a shaft 401 This shaft is journaled in a hracket' l clamped to the post 5 by a set screw 42 or the like. Said shaft is provided with a sprocket wheel i?) to receive a sprocket chain 44 trained over the sprocket attention. of passers-by may be attracted to dial spokes, two sprocketwheels on said post the machine by the changeable exhibitor, which pro ects high enough above the machine for that purpose, and not-depend on thenovel moiement of themachine to attract attention. lVloreover, the signs change with frequent rapidity to hold attention, yet

are stationary long enough to be read with ease. The advertising medium may be of any kind desired, either applied directly to the character of machine on or with which it is used, or to allied or other subjects. hen the advertising device is used alone, any subject-matter of the advertising desired may be used, as the cardsl are removably connected with the member 3 by inserting their ends between the strips .12 and the bent ends 15 of the arms 13, or the cards may be held in place by clips 45, as shown in Figs. 2 and 4e.

In addition to the changeable signs, I may use a fixed or stationary one, as by providing a frame 46 extending over the top of the casing 1 and secured to the same in any preferred manner.

With the changeable signs, I may use a bell 47, carried by acollar 48 fixed by a set screw or the like to the post 5. hammer 49 of said bell is at the lower end of an arm 50 pivoted on the collar 48, as shown in Fig. 5. arm 50 extends in the path of movement of the spokes 13 and is moved thereby to ring the bell each time the member 3 is moved 7 The post 5 is-made to change the sign. hollow to allow the wires or conductors 51 to be led up to the lamp socket 19.

While I have shown and described in detail an advertising device of my invention, it is of course to be understood. that the details of construction and arrangement of parts shown may be variously modified and changed without departing from the spirit and scope of my invention.
